Why is this file locked? I can't save it for future reference and have to come here every time I need to consult one of these pictures. Both this and volume one from the same source are locked. You have volume 1 from another source which isn't locked. Do I need to go photograph this myself? Having these on electronic file is a terrific time saver, but not if I have to seek it out on the web every time I need to check something.
